Here goes another token challenge.

The swf:

http://77231864591d8245d027-dbd663cdd4719bbeb13e13f9ee6e6f1f.r39.cf5.rackcdn.c om/bba.swf

Testing site:

http://cricfree.tv/update/skys1.php

It can be done with RABCDASM like in http://stream-recorder.com/forum/showpost.php?p=63568&postcount=16 but they have added another obfuscation layer, obfuscating a binary inside the swf.

Feel free to add suggestions or any helpful info.

[gorilla.maguila]

Just for fun they have included nice messages inside the swf :D :

If you see this message because you are probably a bad guy. For more info go OUT!!

[peterpan]

They can run, but they cannot hide ;) Check your inbox...

That's great. What method did you use? Dumping memory, dissasembling..etc?

They can run, but they cannot hide ;)

Can you please give me some info as I cant dump my sky films streams now, any pointer or directions would be good,
Thanks in advance for any help :)

UPDATE: got a dump but still not running in rtmpdump, output bellow!

[P3T3]

Any one help me with getting the last challenge please? I am a bit new at dumping I dont ask to be spoon feed, just a hand would be good :D

[spacechild]

I'd be very interested in it as well, because I notice that some public streaming services are adopting this "obfuscation" technique, in order to hide their token (which is a nonsense, as they are free public services and should freely allow the streaming capture).
And I tried to identify the string "secureTokenResponse" in the decompiled swf, obviously without success...
I will send a pm with the hope to find out the right strategy to solve this new issue...
Thanks in advance for the help

[mckv]

it is not really rocket science just dump and grep

Thanks anyway for the answer, Mckv, but the original post was about the swf player of hdcast, not eucast.
I know that the eucast token is not hard to find.

Here is an example of a channel that is still hosted on Hdcast.org:

rtmpdump -r "rtmpe://46.246.124.24:1935/redirect" -a "redirect" -f "WIN 12,0,0,77" -W "http://77231864591d8245d027-dbd663cdd4719bbeb13e13f9ee6e6f1f.r39.cf5.rackcdn.c om/bba.swf" -p "http://www.hdcast.org/embedlive2.php?u=BST15&vw=640&vh=460&domain=hdfoots.com" -y "BST15" -o "2014-04-11_06-22-53_BST15.flv"

I don't know what really happened, but fortunately now hdcast streams can be dumped again without the need of any "mysterious tokens".

So for the moment the hdcast issue seems solved
